In bash I wrote
echo prefix{t1,t2,t3}suffix
and got
prefixt1suffix prefixt2suffix prefixt3suffix
Is something like this present in PowerShell? List expantion I mean.

There is no automatic expansion, but you can do it easily with ForEach-Object cmdlet or array's ForEach method in PS 4 and higher:
't1', 't2', 't3' | ForEach-Object {'prefix' + $_ + 'suffix'}
@('t1', 't2', 't3').ForEach({'prefix' + $_ + 'suffix'})

It is not a solution, but nice enough. Thanks.

@OlegG I'm curious, do you have any specific reasons, that require the list expansion to be absolutely the same as in bash? Because I believe that internally bash loops through the collection too, there is no other way to do it. PowerShell just doesn't have this particular shortcut, that's all.

Just compare Bash command line
vim -d /some/directory/file{1,2}.ps1 with that I have write in PowerShell and you'll see my reason.beatcracker
@OlegG I see. It's true, despite its name PowerShell is really lacking in the "shell" aspect. Perhaps you could try PSReadline module - it really tries to bring a *nix shell expirience to the PS (no list expansion, though).
A couple of other ways are:
't1', 't2', 't3' | % {"prefix$($_)suffix"}
and
't1', 't2', 't3' | % {'prefix{0}suffix' -f $_}

"t1","t2","t3" | % { "prefix" + $_ }
